Resumo: | Ilex paraguariensis St.Hil., popularly named erva-mate in Brazil, is an indigenous species of the Araucaria Forest with a large geographic distribution and a high social and economic importance. The seeds of this species exhibits physiologic and seed coat impermeability dormancies and needs stratification on sand in order to break them. This work aimed to evaluate the influence of genotype -environment interaction on embryo development of erva-mate seeds formed under different environmental conditions. The fruits were collected in Cascavel, Toledo and Campo Mourão, State of Paraná, and in Soledade, State of Rio Grande do Sul, in February 2003. The experiment was carried out on Forest Seed Laboratory of Embrapa Florestas, in a completely randomized design with four replications of 25 seeds each. It was concluded that the seeds from State of Paraná provenances presented more developed embryos than those ones from the State of Rio Grande do Sul, probably as a response of the higher mean annual temperature and the amount of sunlight. |

As sementes desta espécie germinam em surtos desuniformes, pois apresentam dormência tegumentar e fisiológica, requerendo um período de estratificação em areia. O trabalho objetivou avaliar o desenvolvimento dos embriões das sementes de erva-mate, oriundas de diferentes procedências do Sul do Brasil. Os frutos foram coletados em fevereiro de 2003 nos municípios de Cascavel, Toledo e Campo Mourão, no Paraná, e Soledade, no Rio Grande do Sul. O experimento foi conduzido no laboratório de Análise de Sementes da Embrapa Florestas, em delineamento inteiramente casualizado com quatro repetições de 25 sementes cada. Concluiu-se que as procedências do Estado do Paraná apresentaram sementes com embriões mais desenvolvidos do que aquelas oriundas da procedência do Rio Grande do Sul, provavelmente em decorrência das temperaturas médias anuais mais altas e maior insolação.Embrapa Florestas2010-06-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/134Pesquisa Florestal Brasileira; n. 54 (2007): jan./jun.
